Acupuncture Intervention for Alzheimer's

Check if the same lab product or an alternative is used in the 5 most similar protocols
Twenty-four 8-month-old SAMP8 male mice were divided into three groups (n = 8 per group): Alzheimer's disease control (AD) group, the manual acupuncture (MA) group, and the medicine group (M) group. Eight 8-month-old SAMR1 male mice were used as the normal control (N) group.
In the MA group, the mice were immobilized in mouse bags. MA on Baihui (GV20) and Yintang (GV29) was applied for 20 min, with transverse puncturing at a depth of 2-3 mm; then, the mice were pricked at Shuigou (GV26) with disposable sterile acupuncture needles (0.25 mm × 13 mm) (Beijing Zhongyan Taihe Medicine Company, Ltd). During the MA on Baihui (GV20) and Yintang (GV29), twirling manipulation was applied every 5 min and lasted 15 s each time. Each needle was rotated bidirectionally within 90° at a speed of 180°/s. The selection of the acupoints was based on findings from our previous studies [23 (link), 24 (link)]. For the M group, donepezil hydrochloride tablets (Eisai China Inc., H20050978) were crushed and dissolved in distilled water and were delivered to mice by oral gavage at a dose of 0.65 μg/g [25 (link)]. The above treatments were administered once a day for 15 consecutive days, but no treatment was carried out in the N or AD groups. The mice in the AD, N, and M groups received the same 20-min restriction as the MA group.

8 SAMR1 male mice were used as the normal control (Control group) and 24 SAMP8 male mice were randomly divided into three groups (n = 8 per group): AD model control group (AD group), drug group (Drug group), and Electroacupuncture group (EA group). In the Drug group, donepezil hydrochloride tablets (Eisai China Inc., H20050978) were dissolved in distilled water and delivered to mice by oral gavage at a dose of 0.65 μg/g. In the EA group, mice were immobilized in mouse bags. Baihui (GV20) and Yintang (GV29) were chose for electroacupuncture for 15min per day, with transverse puncturing at a depth of 4–5 mm using disposable sterile acupuncture needles (0.25 mm × 13 mm) (Beijing Zhongyan Taihe Medicine Company). The needles were taped and connected to the HANS- LH202 electroacupuncture device (Peking University Institute of Science Nerve and Beijing Hua Wei Industrial Development Company, Beijing, China), with the sparse wave at 2 Hz, 2 V, and 0.1 mA. The mice in the Control group, AD group, and Drug group received the same 15-min restriction as the EA group.

Ten SAMR1 male mice were placed in the control group, and 30 SAMP8 male mice were randomly divided into three experimental groups of 10 mice each: the AD model control group (AD group), drug group, and electroacupuncture group (EA group). In the drug group, donepezil hydrochloride tablets (Eisai China Inc., H20050978) were dissolved in distilled water and delivered to the mice by oral gavage at a dose of 0.65 μg/g. In the EA group, mice were immobilized in mouse bags. Baihui (GV20) and Yintang (GV29) were chosen for electroacupuncture for 15 min per day, with transverse puncturing at a depth of 4–5 mm using disposable sterile acupuncture needles (0.25 mm × 13 mm) (Beijing Zhongyan Taihe Medicine Company). The needles were taped and connected to the HANS-LH202 electroacupuncture device (Peking University Institute of Science Nerve and Beijing Hua Wei Industrial Development Company, Beijing, China), with the sparse wave at 2 Hz, 2 V, and 0.1 mA. The mice in the control group, AD group, and drug group received the same 15-minute restriction as those in the EA group.

Thirty SAMP8 mice were divided into three groups (n = 10 per group): the AD group, the MA group, and the medicine (M) group. Ten SAMR1 mice were used as the normal control (N) group.
In the MA group, the mice were immobilized in mouse bags. MA on Baihui (GV20) and Yintang (GV29) was applied for 20 min, with transverse puncturing at a depth of 2–3 mm. The disposable sterile acupuncture needles (0.25 mm × 13 mm) (Beijing Zhongyan Taihe Medicine Company, Ltd.) were used. During the MA on Baihui (GV20) and Yintang (GV29), twirling manipulation was applied every 5 min and lasted 15 s each time. Each needle was rotated bidirectionally within 90° at a speed of 180°/s. For the M group, donepezil hydrochloride tablets (Eisai China, Inc., H20050978) were crushed and dissolved in distilled water and were delivered to mice by oral gavage at a dose of 0.65 μg/g (Geerts et al., 2005 (link)). The above treatments were administered once a day for 15 consecutive days, with no treatment of the N or AD groups. The mice in the N, AD, and M groups received the same 20 min restriction as the MA group. The duration of MA and selection of the acupoints was based on findings from our previous studies (Jiang et al., 2015 (link), 2016 (link), 2018 (link); Cao et al., 2017 (link); Ding et al., 2017 (link)). The above intervention lasted throughout the Morris water maze test period.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
